Couldn't try the new prop because the damn anode was in the way. I had a flat anode but, not the tools to change it. So, I just went for a nice boat ride with the current prop.

I'll go back up this week (with tools) and give 'er another go.

Okay, so I finally got the Solas HR4 19p bolted up.

As a recap; I love everything about the current High Five 19p prop but, I can only get 4,100 rpm at WOT and I would like to stretch the engine's legs to the Merc specified 4,800 (she's been dyno'd to 5,200). The theory was that one less blade would give me back 150-200 rpm.

The HR4 was bogging the engine just a touch out of the hole and I lost 1,000 rpm on the top end! Although it is 4 blades instead of 5, the diameter is 1" longer (14.25) so, all that surface area + some is back.

Back to my High Five 19p (13.25) for now.

I don't know whether I should re gear from 1.47:1, to where it should be at 1.65:1 and then start prop foolin'.... Or, just bite the bullet and either go to a 17p High Five or, have my prop re-worked or, just keep trying more props.
